HP Scalable Visualization Array Software - Manual (Page 47)

6 Application Examples
This chapter describes the steps to start several representative applications that vary in their
structure and requirements:
• A workstation application that is launched remotely to use only a single node in the SVA.
See
Section 6.1 .
• An application that uses render and display capabilities of the SVA (for example, ParaView).
See
Section 6.2 .
• A workstation application that uses Chromium software and DMX to display on multiple
tiles using the SVA. See
Section 6.3 .
Table 6-1 summarizes the differences among three application scenarios, detailed in the following
sections.

6.1 Running an Existing Application on a Single SVA Workstation
This section describes the main steps and considerations to get an application that already runs
on a single workstation to run on a single node within an SVA. Control takes place using a
workstation remote to the cluster.
6.1.1 Assumptions and Goal
This example assumes you have a visualization application that currently runs on a single
workstation. It also assumes that you have not specifically modified it to take advantage of the
parallel features of a cluster.
